vpars

Jacques Carriere — Tue, 11 Jul 2006 08:10:26 GMT

Can someone tell me what command to use to display all the memory on a server setup with virtual partitions. The command "vparstatus" gives me a good breakdown per virtual partition, but it doesn't give me the total amount of memory in the box.

I think this command will give you the value, even in a vpars environment:

echo "selclass qualifier memory;info;wait;infolog" | /usr/sbin/cstm

But you can also run

vparstatus

to see all the bound memory
and

vparstatus -A

to see the unbound memory.

My favorite way to see the total memory is:

HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]
then
MYSYMBOL="phys_mem_pages"
else
MYSYMBOL="physmem"
fi

MYMEM=$(echo "${MYSYMBOL}/D" \
| adb $HPUX /dev/kmem \
| grep "${MYSYMBOL}: *." \
| awk '{printf "%.0f MB\n",$2/256}')
echo $MYMEM

However, in a VPars situation, this will only report what is available to the partition it is run in. As far as I know, none of the usual techniques will show the total memory available to all partitions.

this gives me total physical memory.

echo "selclass qualifier memory;info;wait;infolog" |/usr/sbin/cstm

vparstatus -A

and look at the ending for available resource information. if you need to expand memory, read the required increments and if you use SuperDome be find the requirements for "interleaving" memory banks/sizing.

Hi Jacques ,

You can use this command :

# vparstatus -v | grep -e Name -e "Total Memory"

Output will be like this :
-------------------------------
Name: vpar01
Total Memory (MB): 10240
Name: vpar02
Total Memory (MB): 4096

Cheers,
Raj

Torsten - selclass ... gives me the info
Pete - the echo adb portion of your script doesn't work

Tom - vparstatus -A doens't give me total memory

Raj - vparstatus -v | grep -e Name -e "Total Memory" doesn't doesn't give me anything. I have an ia64 hp server rx7620(8-way).

Asif - you are right - this works.

thanks guys . Jacques

thanks to all who participated. Jacques
